STEEL FRAMED FIRE RESISTIVE COVERING UNIT

摘要

PROBLEM TO BE SOLVED: To provide a steel framed fire resistive covering unit excellent in fire resistance, at the same time, greatly improving workability at a site and facilitating the connection between members in the case of designing because of a thin wall member. SOLUTION: The steel framed fire resistive covering unit 1 is so constituted that a laminating body 10 of a metal plate 11 and a heat insulation expansive sheet 12 is bent-up worked into an L-shaped section and that slidable seam fitting sections 13 and 14 are respectively provided to both ends of the metal plate 11.
